Tohatsu 40 HP TLDI

So a 1994 M40D can be turned into a 50 hp?

What kind of cost is involved in that? Is it worth it to do to a 19 year old motor. My coworker has one.

Yes it can, but, I would guess that corrosion has gotten the better of that motor. Nearly all of the Megas have had block replacements, they were 93 models. It started about 4 or 5 years ago. The block corrodes around the sleeves so badly, the head gasket won't seal. All of the water jacket cover bolts break off when you try to remove them, makes it kinda futile to spend that much money on a unit with a very limited life span.
